Impact of left ventricular diastolic function and survival in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement

In year 2016, the American Society of Echocardiography (ASE) and the European Association of Cardiovascular Imaging (EACVI) updated Recommendations for the assessment and grading of diastolic dysfunction (DD). We aimed to assess the applicability of this DD grading method and its association with prognosis in patients with severe aortic stenosis (AS) who underwent transcatheter aortic valve implantation (TAVI). We retrospectively identified 237 consecutive patients with severe AS who underwent trans-femoral TAVI. Baseline transthoracic echocardiography was evaluated to assess pre- and post-TAVI diastolic function according to the current ASE/EACVI Recommendations. Prior to TAVI, 41 (17%) patients were diagnosed as having grade I DD, 111 (47%) patients had grade II DD, 80 (34%) had grade III DD. DD grade after TAVI decreased (p
